In previous studies, we presented a two-line system for producing hybrid varieties in common wheat (Triticum aestivum L.) based on photoperiod-sensitive cytoplasmic male sterility (PCMS) caused by the cytoplasm of relative wild species Aegilops crassa L. We have developed several promising elite PCMS lines with the genetic background of Japanese wheat cultivars, which showed high cross-pollination fertility and high male sterility under long-day conditions and high seed fertility under short-day conditions. Here, we performed an F1 seed production trial between eight elite PCMS lines and the pollinator variety ‘Fortunato’, which has high combining ability with the PCMS elite lines, under long- day conditions in Hokkaido, Japan. -

New Insights on Bidens Herzogii (Coreopsideae, Asteraceae), an Endemic Species from the Cerrado Biogeographic Province in Bolivia

Apartado postal 1-139, Zapopan 45101, Jalisco, México. Abstract The morphological limits among some Coreopsideae genera in the Asteraceae family are complex. An example is Bidens herzogii, a taxon first described as a member of the genus Cosmos, but recently transferred to Bidens. The species is endemic to Eastern Bolivia and it grows on the Cerrado biogeographic province. Recently collected specimens, analysis of herbarium specimens, and revisions of literature lead us to propose new data on morphological description and a chromosome counts for the species, a tetraploid, where x = 12, 2n = 48. Lastly, we provide data on geographic distribution and niche modeling of B. herzogii to predict areas of endemism in Eastern Bolivia. This area is already known for this pattern of endemism, and the evidence generated can be used to direct conservation efforts. -

INTRODUCTION Pollination in hybrid vegetable seed production is the transfer of pollen from the anthers of the male fertile flowers to the stigma of the male sterile (female) flowers. The pollination phase has a significant impact on final seed yield and quality. In many vegetable crops, such as onion (Allium cepa), carrot (Daucus carota), cabbage (Brassica oleracea), cauliflower (B. oleracea) and radish (Raphanus sativus), pollination is performed mainly by honey bees (Apis mellifera). However, although it is the main managed pollinator, there are other wild and managed pollinators that can be of significant commercial value. Pollination quality is expressed as the quantity of pollen moved to the female flower; this depends on the pollinators’ activity and their mobility between the flowers of the two lines. 2. OBJECTIVES This document details the essential points in using pollinators for commercial hybrid seed production: Honey bee hive management and colony (populated beehive) strength regulations. -
